annotate Discovery/Src/simulation.c @ 1026:5fedf7ba2392 GasConsumption
Added text based edit item:
In previous version only numbers could be entered as data field. This changes introduces a edit field for entering text in upper characters. '_' are used for seperation because simple white spaces (' ') would cause problems in the handling of the edit field. String length is limited to eigth charecters.
